MySQL lookups in mapping

You can create lookups for objects using a MySQL connection. You can retrieve data from a MySQL lookup object based on the specified lookup condition.

When you configure a lookup in MySQL, you select the lookup connection and lookup object.

You can't configure a Lookup transformation in a data transfer task.

The following table describes the MySQL lookup object properties that you can configure in a Lookup transformation:

Property	Description
Connection	Name of the lookup connection. You can select an existing connection, create a new connection, or define parameter values for the lookup connection property. If you want to overwrite the lookup connection properties at runtime, select the Allow parameter to be overridden at run time option. Specify the parameter file directory and name in the advanced session properties.
Source Type	Type of the MySQL lookup object available. You can choose from the following lookup object types: Single Object Parameter
Parameter	A parameter file where you define values that you want to update without having to edit the task. Select an existing parameter for the lookup object or click New Parameter to define a new parameter for the lookup object. The Parameter property appears only if you select parameter as the source type. If you want to overwrite the parameter at runtime, select the Allow parameter to be overridden at run time option. When the task runs, the Secure Agent uses the parameters from the file that you specify in the advanced session properties.
Lookup Object	Name of the MySQL lookup object.
Multiple Matches	The behavior when the lookup condition returns multiple matches. You can select one of the following options: Return first row Return last row Return any row Return all rows Report error
